As Chauncey Cohen, a little boy who loved cars, was buried this week amid lingering questions about his suspicious death, the state is investigating alleged abuse or neglect in the home.

A spokesperson for the state Department of Children and Families said Wednesday the department has received a Chapter 51A report on behalf of the 4-year-old boy, and is currently investigating.

Meanwhile, investigators have released no new details in the case and are asking anyone with information for help.

One expert in forensic pathology, who spoke generally, said news of a child’s death may or may not suggest foul play: that’s for an autopsy to determine.

“The main point that people may or may not realize, is just because it’s a child that died, doesn’t mean that it was necessarily foul play,” said Dr. Ernest P. Chiodo, a physician, attorney, toxicologist and biomedical engineer who once served as chief physician for city of Detroit.

Toxicology results typically can take several days, or as long as a couple of weeks, according to Chiodo.

The boy’s autopsy results are still unknown, pending toxicology reports, Peter Maguire, who spoke for Plymouth County District Attorney Timothy Cruz, confirmed Wednesday.

On June 2, the boy’s mother, 26-year-old Tania Merisca, of Sterling Road, told police her son became unresponsive while she gave him a bath.

Merisca drove him to Good Samaritan Medical Center, where he was pronounced dead about an hour later, at 9:26 p.m.

“I need to know what happened to my son,” Merisca told reporters the next day through tears, adding she had left her son with her boyfriend, whom she identified as Antonio Durham, of Brockton, that day when she left for work.

Meanwhile, family members gathered Tuesday to lay the boy to rest.

A funeral service was held in the Home of Funeraries Multi Culturel. Burial at Melrose Cemetery followed.

The DA’s office has declined to comment on a timeline or on whether “suspicious circumstances” implied foul play.

Merisca has been unable to be reached for comment. Multiple family members declined to comment Wednesday.

Authorities ask that anyone with information contact Brockton police at 508-941-0234, or state police at 508-947-8087.
